Vent controlling nursing unit



Sept- 1 1956 Y. H. KURKJIAN VENT CONTROLLING NURSING UNIT Filed Oct. 17,1955 INVENTOR YER VAN? ffuRKu/A N fl/SATTORNEY United States Patent VENTCONTROLLING NURSING UNIT Yervant H. Kurkjian, Clifton, N. J. ApplicationOctober 17, 1955, Serial No. 540,863 1 Claim. (Cl. 215-11) Thisinvention relates to a nursing unit, and has for one of its objects theproduction of a simple and efiicient controlling means for a flexiblevented flange nipple, in the nature of a channel formed in the nippleflange and communicating with a venting means in the flange, the flangedirectly contacting the cap to automatically seal the venting means whennursing is discontinued.

A further object of this invention is the production of a simple andeflicient vented flange nipple in combination with a cap, the flange ofthe nipple having a channel communicating with a vent, and the capengaging the flange inwardly of the channel and close to the neck of thenipple to automatically seal the venting means when nursing isdiscontinued.

The present invention is a modification of the structure shown in myapplication relating to a Nipple Carrying Vent Controlling Ring, filedFebruary 24, 1953, Serial Number 338,545.

Other objects and advantages of the present invention will appearthroughout the following specification and claim.

In the drawing:

Figure l is a side elevational view of the nursing unit, certain partsbeing shown in section; and

Figure 2 is a top plan view of the nipple forming part of the nursingunit.

By referring to the drawing by numerals, it will be seen that designatesa container having a large open end upon which a cap 11 is removably andadjustably secured or threaded. The cap 11 is provided with an inturnedintegral sealing flange 12 having a circumferential flat sealing face13, constituting a nipple flange engaging means.

A flexible or rubber nipple 14 having a flexible annular and lateralnipple flange 15 is carried by the container 10. The flange 15 isprovided with a circumferential venting channel or recess 16 upon itsouter or upper face, which is located directly under the under or innerface 13 of the flange 12, adjacent and not far from the body of thenipple 14, as is shown in Figure 1. This channel or recess 16 is insetfrom the outer face of the flange 15, and a vent 17 extends through theflange 15 and communicates with the channel or recess 16. The vent hasan open end inset within the channel or recess 16,

2,762,520 Patented Sept. 11, 1956 so that the open end of the vent is atall times out of contact with the nipple flange engaging means or flange12. It should be understood that the venting means may include one ormore aperture vents within the scope of the invention, and that therecess 16 may be of a suitable type to accomplish the purpose of theinvention.

It is important to note that the venting channel 16 is formed adjacentthe neck of the nipple 14, and that the channel 16 communicates withvent 17. The channel 16 is inset from the outer edge of the flange 15,and the flange 15 is provided with a circumferential flat upper sealingface in close proximity to said neck of the nipple for releasablyabutting in flat contact or engagement with the flat inner face 13 ofthe cap flange 12. It should be further noted that the nipple flangeengaging face 13 of the cap flange 12, overlies the channel 16 andcontacts the outer or upper face of the nipple flange 15 interme diatethe channel 16 and the neck of the nipple 14 to normally close or sealthe channel 16. Since the vent is inset in the channel 16, the open endof the vent 17 will be at all times out of contact with the flange 12,thereby preventing clogging of the vent.

The channel 16 defines an air passageway communicating with andoverlying said vent aperture 17 to convey air throughout the length ofsaid passageway to the vent aperture 17 when the sealing face of theflexible flange intermediate the channel 16 and the neck of the nipple14 flexes away from the sealing face 13 of the cap flange 12 at anypoint within the length of said sealing faces adjacent said passagewayduring the process of nursing. Having described the invention, what isclaimed as new 1s:

In combination with a container, a cap adjustably secured to saidcontainer and including an integral sealing flange having acircumferential flat sealing face, a nipple having a neck and flexiblenipple flange, said flexible nipple flange having a circumferential flatsealing face in close proximity to said neck of said nipple andreleasably abutting said flat sealing face of said cap flange, saidnipple flange having a vent aperture therein adjacent said seal ing faceof said nipple flange, one end of said aperture being inset relative tosaid cap flange, said nipple flange having a circumferential channel inthe upper face thereof outwardly of said nipple flange sealing face andproviding an air passageway between said cap flange and nipple flange,said air passageway communicating with and overlying said vent apertureto convey air throughout the length of said passageway to said ventaperture when the sealing face of said flexible nipple flange flexesaway from said sealing face of said cap flange at any point within thelength of said sealing faces adjacent said passageway during the processof nursing.
